IMPROVEMENT IIN,SPINDLES FOR SPINNING-MACHINES.

Specification forming part of Letters .Patent No. 119,032, dated September 19, 1871. i l Y 4section of the same and the bobbin as applied to such. Y

The duplex spindle is composed of a dead or stationary spindle, A, and a live spindle, B, the

latter being tubular and provided with a whirl, G, and arranged on and so as to revolve about the dead spindle. In the drawing the dead spindle A projects upward from the oil-reservoir D, which is tenoned into the rail E, and is to be held in place therein by a clamp-screw screwed laterally into the rail and against the tenon. The oilreservoir, formed internally as shown at a, receives into its upper part an extension or portion, b, of the live spindlethat is to say, a portion of thatl part of it which is shown as projecting below the whirl. The live spindle at its top or upper part is provided with a pivot, o, to run and be supported in a bearing or socket, d, made in the upper end of the dead spindle, the same being so as to suspend the live spindle onthe dead spindle. The two also touch or have a bearing,

f, about on a level with the whirl, the dead spindle above such bearing being made tapering and of a diameter less than that of the bore immediately surrounding it; The bobbin F iits upon -or receives the live spindle in manner as shown in Fig. 2, and is revolved with and by it. The part b extended into the oil-reservoir not only serves as a cap or cover thereto, but to extend the live spindle down into the oil-reservoir in a manner to enable oil, by capillary attraction, to be driven therefrom up into the lower bearing of the live spindle on the dead spindle. In order to effect lubrication of the upper bearing of the two, the live spindle has first to be raised entirely ofiI the dead spindle, the oil being next poured into the step at the top of the latter.

VThe great merits of the duplex spindle are that it requires very little power to run, the external portion of it carrying the bobbin the supporting-surfaces are all well protected from dust and fibrous matters; it is easily lubricated; it will run with very little friction and consequent wear; and does not require any removal of the bobbin from the part on which it is directly supported in order to enable the running parts to be duly oiled. The oil does not waste from it, as in many other spindles, and is not liable to be thrown upon the floor or frame or other parts of the spinningmachine.

I am aware of the several inventions described and represented in the patents 7 ,028 of Reed, and in the rejected application of Cocker, filed October 2l, 1847 5 Goodall, filed March 20, 1859; Kivet, filed April 25, 1853, and Johnson, filed May 1, 1869, and make no claim to any thing or things, arrangement, or combination of parts shown in either of such cases. Although I employ a tubular live spindle to encompass and operate with a dead or stationary spindle, and to enter the oil-reservoir or bolster for supporting the dead spindle, I construct and combine the several parts in such manner as to cause them to operate to better advantage than when made and applied as shown in the said patent or either ofthe said rejected applications; as, for instance, instead of making the pivot at the end of the dead spindle,

I form a cavity or step therein to hold oil and to receive a pivot to project down from the head of the live spindle, thereby causing the head of the live spindle to serve as a cover to the said cavity, and the latter to retain the oil against the rubbing-surfaces of the pivot and cavity. Furthermore, by the peculiar construction of the oilreservoir and application of the live spindle to it the oil-reservoir is capped or covered independently of the whirl, and such cap or cover fits to the live spindle, and the latter is extended down into the reservoir. Under such circumstances the live spindle aids in covering the oilreservoir, besides serving, as described, to cause oil to be drawn by capillary attraction up into the lower bearing. In Johnson and Gockers spindles the lower bearing depends on the upper one for its oil, the upper, on account of the oilcavity being in the live spindle, being liable to soon lose its oil, run dry, and heat, which is not the case with my improved arrangement. Each bearing, wherein the oil-reservoirs of both bearings are closely capped to prevent dust from getting into them, is independent of the other, and the lower bearing derives its oil from the bolster reservoir by capillary attraction. Furthermore, any spent oil from the upper bearing flows down into the lower bearing, and, if in excess of what is there required, Will iiow into and be caught by the oil-reservoir a.

The dead spindle A, from the lower bearing f, tapers upward, so as not to touch the bore ofthe live spindle B except at the bearing j, Where the spindles are cylindrical. Thus the draft of the band on the Whirl will cause the two spindles to bear together only at the bearing j', in consequence of Which the friction incident to operating` the live spindle Will be very little to what it
